VENTILATED WALL Filed Sept. 13, 1949 ATTEI RN EYS Patented July 21, 1953 1 Claim.

This mant es rages to rt a r -bu d and more particularly to a molding'for use with an insulated Wall of a building.

The object of the invention is to provide a molding which is adapted to. be attached to an insulated wall of a building'whereby moistureladen air can pass throughthe molding so that the moisture will not damage the paint on the outside of the building.

Another object of the invention is to provide an insulated wall construction for a building, the

'I he present invention directed to a molding member whereby moisture laden. air can .pass

wall construction including siding that is spaced from an insulated panel member, the molding of the present invention being perforated and communicating with the space between the siding and the panel member, whereby moistureladen air can pass from this space to the outside so that this moisture will not damage the paint on the outside of the building.

A further object of the invention is to provide a molding which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this application, and in which like numerals are used to designate like parts throughout the same;

Figure l is a vertical transverse sectional view taken through the insulated Wall, with the molding of the present invention attached thereto;

Figure 2 is an enlarged vertical sectional view taken through one of the molding members;

Figure 3 is a fragmentary bottom plan view of the molding member of Figure 2;

V Figure 4 is a fragmentary perspectiveview of one of the molding members.

Referring in detail to the drawings, there is shown a portion of a building which includes a roof [0, the building including the usual side panels or inside boards I I. A layer of insulation I2 is arranged contigous to the outer surface of the side panel I I, Figure 1. The building further is provided with a concrete footing l3 that supports the sill Hi, there being floor boards l5 extending along the bottom of the building. Suitable joists l6 are supported on the sill l4.

The building construction further includes a sheathing I1 that has shingles or siding 18 seout from the space I9 so that the'moisture therein will not damage the paint on the shingles Thus, by providing a ventilation or 'escape means for the moisture, the moisture will not pass through the sheathing I1 and shingles [8 to cause the paint to work loose from the shingles l8. I

In actual use, both the upper and lower ends of the siding I! have projecting therefrom the molding members which are designated by the numeral 20. Each of the molding members 20 includes a body portion, and the body portion comprises a top section 2| and a bottom section 22 which is arranged in spaced parallel relation The molding member below the top section 2!. 20 is preferably fabricated of a rusteresistant material, such as aluminum or other metal or the molding member can be made ofany suitable material. The ends of the top and bottom sections 2| and 22 are connected together by an arcuate section 23, Figures 2 and 4. Extending from the top section 2| and secured thereto, or formed integrally therewith, is a flange or lip 24, while extending from the bottom section 22 is a similar flange or lip 25. The bottom sec- ,tion 22 is provided with a plurality of perforacured to the outer surface thereof. The sheathing I! is spaced from the layer of insulation l2, and the space defined between the sheathing l1 and the insulation I2 i indicated by the numeral I9.

tions or openings 26 therein, so that the mois-. ture-laden air can pass from the space I9 through the openings 26 and to the outside.

From the foregoing, it is apparent that a molding member has been provided for use with an jected through the cut-away portions of the sheathing and shingles. The lips 24 and 25 engage the inner surface of the sheathing H to prevent the molding members 20 from accidentally working loose from the wall construction. Then, moisture-laden air which accumulates in the space H) will travel in the direction of the arrows and this moisture-laden air will pass from the space I9 through the openings 26 where it will be dissipated to the outside. moisture in the insulation space [9 will not be absorbed or worked through the siding l1 and shingles l8, 'so that the'moisture will not cause the paint on the outside of the building to work loose.

I claim: I

In a building construction the combination with a panel member, a layer of insulation ar- Thus, this ranged contiguous to the outer surface of said panel member, and a sheathing spaced from said insulation to define a space therebetween, of a pair of moulding members each having a portion thereof arranged exteriorly of said sheathing and extending horizontally along the outer face of the sheathing, said moulding members being arranged adjacent the top and bottom of said sheathing and supported by the latter, said moulding'memb'er'seach comprising a top section extending downwardly and outwardly and arranged angularly with respect to said panel member, a bottom section arranged in spaced parallel relation below said top section, an arcuate SCC- tion connecting said top and bottom sections together, there being a plurality of spaced openings arranged in said bottom section for the egress therethrough of moisture laden air, a first flange extending from said top section; and a second flange arranged in alignment with said first flange and extending from said bottom section. said openings being arranged ,contigousto 4 said arcuate section, said moulding members being secured to the sheathing and communicating with each other through the space defined between the sheathing and the insulation.
